7 9. FOREWORD TO THE ADVANCED USER MANUAL This manual describes the procedures for terminal personalization in order to adapt it to the specific weighing system in which it is installed. It contains the software commands used to interface the terminal with a PC, PLC and host computers in general. WARNING The personalization operations described herein do not in any way influence weighing functions but, unless correctly performed, they may compromise the operation of the system as a whole. The operations described in this section of the manual should only be entrusted to qualified technicians with specialised experience in this field. 2-7

9 10. PROGRAMMING OF SERIAL LINE COMMUNICATION 10.1 Symbols used D430 The following conventions are used to denote the characters used in serial line communication. Normal characters are indicated with their usual symbols. Control characters appear in brackets and are written in uppercase. For example: <CR> indicates the carriage return character. <SP> indicates the space character. <SOH> indicates the character that starts the command in a CW string (par on page 2-17). <STX> indicates the character that starts the response in a CW string (par on page 2-17). <EOL> indicates the character that ends the response in a CW string (par on page 2-17) and can be <CR> or <CR> <LF>. Where necessary, the hexadecimal value of the character is given in numbers and uppercase letters. For example: <CR>(0DH) or $(24H). Variables are written in lower case between brackets. For example: <um>= unit of measurement. The values can be: <SP>g = grams, g= grams in the case of the Checkweight string (par on page 2-15) kg = kilograms <SP>t = tons, t = tons in the case of the Checkweight string (par on page 2-15) lb = pounds oz = ounces Numeric fields are indicated with n and y, and may include initial spaces, a decimal point and a minus sign. 2-9

10 10.2 Strings The terminal has two serial output ports which may be used for the connection of external devices, such as printers, personal computers, PLCs, etc.. The user can choose the type of transmission protocol to be used from among those already present on the terminal. The user may also personalize the serial transmission parameters using the specific menu (see par on page 2-89) Cb (or Bilanciai) string 1 st character $(24H) start string character 2 nd character <s> s=stability s=0 weight stable s=1 weight not stable s=3 weight not valid (negative or overload) 3 rd -7 th net weight character if the weight consists of more than 5 digits, the least significant digits will not be transmitted; 8 th character <CR>(ODH) end string character The following protocols are available: Cyclic (see par on page 2-25), On request (see par on page 2-25), ACK-NAK (see par on page 2-25). 2-10

11 Extended string 1 st character 2 nd -10 th character 11 th character 12 th -20 th character 21 st character 22 nd -23 rd character 24 th character 25 th character 26 th character 27 th character 28 th character 29 th character 30 th character $(24H) <SP>(20H) <SP>(20H) <um> <SP>(20H) <s1> <s2> <s3> <s4> <CR>(0DH) <LF>(0AH) start string character net weight with sign and decimal point (if present) space tare with sign and decimal point (if present) space Unit of measurement space scale status scale status scale status scale status The characters <s1>, <s2>, <s3>, <s4> are ASCII characters that must be interpreted as hexadecimal values. Each character represents 4 bits of different significance; for example, the incoming ASCII character "A" must be interpreted as the hexadecimal digit "A"; bit3 bit2 bit1 0 bit0 2-11

12 When a bit assumes the value "1" the corresponding signal is "true"; the significance of the signals is as follows: <s1> bit 0 minimum weighment signal bit 1 tare locked signal bit 2 tare preset(1)/self-weighed (0) entered signal bit 3 centre zero signal <s2> bit 0 LSB weighing extension signal (ME only) bit 1 weight stable signal bit 2 overload signal bit 3 MSB weighing extension signal (ME only) <s3> bit 0 tare entered signal bit 1 tare locked cancelled signal (ME only) bit 2 weight not valid bit 3 printing in progress <s4> bit 0 approved instrument bit 1 converter fault bit 2 scale configuration parameters error bit 3 not utilised The following protocols are available: Cyclic (see par on page 2-25), On request (see par on page 2-25), ACK-NAK (see par on page 2-25), Remote commands (see par on page 2-26). 2-12

13 Visual string 1 st character 2 nd character $(24H) 0(30H) start string character fixed zero character 3 rd character <s> s=stability s=0 weight stable s=1 weight not stable s=3 weight not valid (negative or overload) 4 th -8 th net weight with sign; character if the weight consists of more than 5 digits, the least significant digits will not be transmitted; if the value includes a decimal point, the length of the string will be increased by 1 character 9 th character <CR>(0DH) end string character 2-13

14 Idea string 1 st character <cis> cis=@(40h) Start string character on pressing cis=$(24h) Start string character in other cases 2 nd character <s> s=stability s=0 weight stable s=1 weight not stable s=3 weight not valid (negative or overload) 3 rd -7 th net weight character if the weight consists of more than 5 digits, the least significant digits will not be transmitted; 8 th character <CR>(ODH) end string character Cma Reserved string, not to be used. Further information supplied on ordering On request with address Selecting this option disables the transmission of cyclic strings. Uses remote commands followed by terminal identification number (see par on page 2-40). 2-14

15 Customized string The string composition can be customised straight from the terminal (see par on page 2-102) or by using the "Dialogic" program. In this case, contact the Manufacturer for further details Checkweight string The length of the checkweight string can vary from 10 to 20 characters. This variability depends on: the unit of measurement used to express the weight: if expressed in g or in t, the unit of measurement only occupies one character in the string; if expressed in kg, oz or lb, the unit of measurement occupies two characters; type of protocol: if cyclic, the weight qualification character (instable, overload, valid and stable) will be included. For the sake of simplicity, only the example of a checkweight string formed by 20 characters has been given, with the weight expressed in kg, oz or lb and the cyclic type of protocol. 2-15

16 1 st character <STX> (02H) 2 nd character <SP> (20H) o <-> 3 rd -8 th character 9 th character 10 th -11 th character 12 th -13 th character 14 th -17 th character <SP> (20H) <um> <GR> or <NT> <OVER> or <ACPT> or <UNDR> Space if the weight is positive Minus sign if the weight is negative weight space unit of measurement (kg, oz or lb) As mentioned previously, if the weight is given in g or in t, the unit of measurement only occupies one character (10 th ), in the string. Consequently, the numbering of the following characters will decrease by one unit. GR = gross weight NT = net weight OVER = ABOVE ACPT = WITHIN UNDR = BELOW 18 th character <M> or M = weight instable <R> or R = overload <SP> (20H) SP = weight valid and stable This character is only present if the protocol is cyclic. The numbering of the successive characters decreases by one unit in all other cases. 19 th character 20 th character <CR> (0DH) <LF> (0AH) 2-16

17 CW string The CW string can only be selected in the Checkweight operating mode and its length can vary from 15 to 17 characters. This variability depends on: the unit of measurement used to express the weight: if expressed in g or in t, the unit of measurement only occupies one character in the string; if expressed in kg, oz or lb, the unit of measurement occupies two characters; type of protocol: if cyclic, the weight qualification character (instable, overload, valid and stable) will be included. For the sake of simplicity, only the example of a CW string formed by 17 characters has been given, with the weight expressed in kg, oz or lb and the cyclic type of protocol. 2-17

18 1 st character <STX> (02H) 2 nd character <SP> (20H) or <-> 3 rd -8 th character 9 th character 10 th -11 th character 12 th -13 th character <SP> (20H) <um> <GR> or <NT> space if the weight is positive minus sign if the weight is negative weight space unit of measurement (kg, oz or lb) As mentioned previously, if the weight is given in g or in t, the unit of measurement only occupies one character (10 th ) in the string. Consequently, the numbering of the following characters will decrease by one unit. GR = or NT = net weight 14 th character <O> or O = OVER = ABOVE <A> or A = ACCEPT = WITHIN <U> U = UNDER = BELOW 15 th character <M> or M = weight instable <R> or R = overload <SP> SP = weight valid and stable This character is only present if the protocol is cyclic. The numbering of the successive characters decreases by one unit in all other cases. 16 th character 17 th character <CR> (0DH) <LF> (0AH) 2-18

19 Piece number string 1 st character 2 nd -7 th character 8 th character $ (24H) character at the start of the string number of pieces <CR> (0DH) character that ends the string Printed Data string 3 transmission modes are available: Single The string is transmitted, after which the data are printed. The On request (see par on page 2-25), ACK-NAK (see par on page 2-25) and On remote commands (see par on page 2-26) protocols are available. If the ACK-NAK protocol is selected, the message "DATA NOT TRANSMITTED" will appear at the bottom of the print in the event of a transmission fault. Spool The data are printed, after which the string is transmitted. The only protocol available is ACK-NAK (see par on page 2-25). If there is a transmission fault, the string is memorized in an archive instead of being transmitted. Whenever a weighing operation must be transmitted, an attempt will first be made to transmit the strings at the end of the archive, then the string pertaining to the current operation. Archive The strings are memorized in an archive after a weighing operation. Transmission takes place following the (<ENQ> (05H)) command. The On request (see par on page 2-25) and ACK-NAK (see par on page 2-25) protocols are available. 2-19

25 10.3 Protocols for cyclic strings ACK-NAK protocol The string is only sent on request of the user via the request transmission key or from an external input (see par on page 2-90). After transmission of the weight, the terminal behaves as follows: if it receives the "ACK" character (06H), it awaits a new transmission request; if it receives the "NAK" character (15H), it sends the string again because the previous transmission was not completed successfully; if it receives three "NAK" characters in succession, the terminal displays the "NO ACK" message (transmission error) Cyclic protocol The selected string (see par on page 2-10) is transmitted cyclically at a rate of 3 times per second On request protocol The selected string is transmitted: either on pressing the request transmission key ; or on the activation of an input (see par on page 2-90). 2-25

26 10.4 Remote commands protocol There are a number of serial line commands with which various operations can be commanded from a remote device (PC, PLC etc.). WARNING Remote commands are only enabled if the extended string format was selected during terminal configuration (see par on page 2-11). WARNING Remote commands are not executed if cyclic serial transmission is in progress; in this case cyclic transmission must be suspended with the command "EX<CR>" before giving any other remote commands. 2-26

27 Response times Key CMD = Remote command ANS = Response to remote command tc = command time. Depends on the number of characters, the number of bits per character and the baud rate. E.g.: XB<CR>; with 3 characters, 8N1, 9600 then tc = 3,3ms trr = response delay time. It is always 2 characters or less. E.g.: with 2 characters, 8N1, 9600 then trr <= 2,2ms tr = response time. Depends on the number of characters in the response. E.g.: if the response at XB<CR> is a string with 16 characters, 8N1, 9600 then tr = 17,6ms ta = waiting time between the end of the response and the beginning of the next command. Must at least correspond to the time of 2 characters. E.g.: with 2 characters, 8N1, 9600 then ta >= 2,2ms Figure Response times (citi0614.jpg) 2-27

28 Remote commands in the version for terminals with several scales If the terminal is for the version with several scales, the syntax of some of the remote commands will change so as to indicate to which scale reference is being made. For example, to request the gross weight, the syntax will be changed in the following way: XBb<CR> where b indicates the letter (A or B) of the scale in question. For these commands, the syntax will be given between brackets alongside the standard command. 2-28

29 Reply to an incorrect command??<cr><lf> This reply string is sent: if the command syntax is incorrect; if the command cannot be executed Reply to a correct command In the case of the command being accepted, if the command requests the transmission of information, the reply will consist of the transmission of the requested data item; in other cases the reply will consist of the following string: OK<CR><LF> Suspension of cyclic transmission This command is not available with the RS485 protocol, in which transmission is on request only EX<CR> Resumption of cyclic transmission This command is not available with the RS485 protocol, in which transmission is on request only SX<CR> Request for gross weight XB<CR> (XBb<CR>) The terminal responds with the following string: n<sp><um><sp>b<cr><lf> n = 9 characters (see par on page 2-9). 2-29

30 Request for net weight XN<CR> (XNb<CR>) The terminal responds with the following string: n<sp><um><sp>nt<cr><lf> n = 9 characters (see par on page 2-9) Request transmission of tare XT<CR> (XTb<CR>) The terminal responds with the following string: n<sp><um><sp>te<cr><lf> if the tare has been entered manually; n<sp><um><sp>tr<cr><lf> if the tare has been acquired. n = 9 characters (see par on page 2-9) Request transmission of scale status XZ<CR> (XZb<CR>) The terminal responds with the following string: <s1><s2><s3><s4><cr><lf> The characters s1, s2, s3 and s4 are ASCII characters which must be interpreted as hexadecimal values. Each character represents 4 bits of different significance; for example, the incoming ASCII character "A" must be interpreted as the hexadecimal digit "A"; bit3 bit2 bit1 0 bit0 2-30

31 When a bit assumes the value "1" the corresponding signal is "true"; the significance of the signals is as follows: <s1> bit 0 minimum weighment signal bit 1 bit 2 bit 3 tare locked signal tare preset(1)/self-weighed (0) entered signal centre zero signal <s2> bit 0 LSB weighing extension signal (ME only) bit 1 bit 2 bit 3 weight stable signal overload signal MSB weighing extension signal (ME only) <s3> bit 0 tare entered signal bit 1 bit 2 bit 3 tare locked cancelled signal (ME only) weight not valid printing in progress <s4> bit 0 approved instrument bit 1 bit 2 bit 3 converter fault scale configuration parameters error not utilised D

32 Request transmission of scale status (version EV2001) XS<CR> (XSb<CR>) In the case of a positive reply, the terminal responds with the following string: <s1><s2><cr><lf> The characters s1 and s2 are ASCII characters that must be interpreted as hexadecimal values. The bits indicate the scale status as follows. <s1> bit 0 in range bit 1 bit 2 bit 3 weight stable centre zero displayed net weight <s2> bit 0 not utilised bit 1 bit 2 bit 3 not utilised not utilised print request: the print key has been pressed or input n 3 is activated Scale zeroing AZ<CR> (AZb<CR>) Tare acquisition AT<CR> (ATb<CR>) Tare entering nat<cr> (natb<cr>) The command AT must be preceded by a weight expressed in a maximum of 7 characters comprising the decimal point, if present. 2-32

33 Cancellation of an entered tare CT<CR> (CTb<CR>) This command cancels any tare value in memory Request transmission of general data table ND<CR> The terminal responds to this command with a sequence of strings terminating in <CR><LF> each containing the number of the data item and its description; the following is an example data table: 1 Date 2 Time 3 Extracted 4 Gross 5 Tare 6 Net 7 Status The value of the general data in the table can be recalled and set up with the remote commands described in par on page 2-33 and par on page Request for general data item "n" Xln<CR> With this command it is possible to read the current value of any of the general data. 2-33

34 Request to enter the value "y" in the general data item "n" yxln<cr> where "y" is the value you wish to assign to the data item "n". Obviously the value to be entered must conform to the format of the data item. Values for some of the general data cannot be entered (e.g. gross weight, net weight, scale status, date, time, totals, etc.) Request for transmission of the net weight and the scale status Xn<CR> N.B.: the command sent is comprised of an uppercase X and lowercase n (not to be confused with generic significance assigned to the lowercase n described in par on page 2-9). In the case of a positive reply, the terminal responds with the following string: n<sp><um><sp><s1><s2><s3><s4><cr><lf> n = 9 characters (see par on page 2-9). The characters s1, s2, s3 and s4 are ASCII characters the meaning of which is explained in par on page

35 Request for transmission of net weight and scale status with 6 bytes YS<CR> (YSb<CR>) When the command is received, the terminal replies with the following string: n<sp><um><sp><s1><s2><s3><s4><s5><s6><cr><lf> n = 9 characters (see par on page 2-9). The meaning of the <s1>, <s2>, <s3> and <s4> bits is described in par on page The meaning of the <s5> and <s6> bits is as follows: <s5> bit 0 not utilised bit 1 bit 2 bit 3 not utilised battery low indication <s6> bit 0 tare changed bit 1 bit 2 bit 3 Print made, weight acquired not utilised not utilised not utilised The bit2 of <s5> is zero-set immediately after the 6 byte status transmission. The bit3 of <s5> is zero-set immediately after the CP remote command has been received (par on page 2-36). You can read the last weight acquired by means of the PA command (par on page 2-36). The bit0 of <s6> is zero-set after the response has been transmitted to remote command XT (par on page 2-30) or YT (par on page 2-36). Remember that in multi-expansion terminals, the tare is rounded off to the extension change but the changed tare bit is not altered (the operator must ask for the tare whenever the extension changes; this change can be checked through bit0 and bit3 of <s2>). 2-35

36 Request for transmission of the net weight, tare and scale status with 6 bytes YT<CR> (YTb<CR>) When the command is received, the terminal replies with the following string: n<sp>y<sp><um><sp><s1><s2><s3><s4><s5><s6><cr><lf> where: n = net weight; n = 9 characters (see par on page 2-9) y = tare; y = 9 characters (see par on page 2-9) The meaning of the <s1>, <s2>, <s3>, <s4>, <s5> and <s6> bits has been described previously (par on page 2-35 and par on page 2-30) Print request PR<CR> Any "printing not performed" message will be signalled only on the display Read last weight acquired PA<CR> The terminal responds by sending the last net weight to be acquired by pressing the print key or in response to the remote command PR; the reply string is as follows: n<sp><um><sp>pa<cr><lf> n = 9 characters (see par on page 2-9) Cancel last acquired weight CP<CR> 2-36

37 Request division value Xe<CR> (Xeb<CR>) The terminal responds with the string: e= n<sp><um><cr><lf> Request for net weight in high resolution YN<CR> (YNb<CR>) The reply string is: n<sp>y<sp><um><sp><s1><s2><s3><s4><cr><lf> n= net weight; n = 9 characters (see par on page 2-9) y= net weight in high resolution; y = 10 characters (see par on page 2-9) s1,s2,s3,s4=see STATUS in extended string (par on page 2-11) Request for maximum capacity value XM<CR> (XMb<CR>) The reply string is: Max= n<sp><um><cr><lf> n = 9 characters (see par on page 2-9) Request for net weight without unit of measurement YP<CR> (YPb<CR>) The reply string is: n<cr><lf> where: n= significant digits of weight only This string does not include the unit of measurement and insignificant leading zeroes are not transmitted. 2-37

38 Lock keypad and display LD<CR> The message "DISPLOCK" is displayed in place of the weight and all keys are disabled Unlock keypad and display UD<CR> The keypad and display are re-enabled Lock keypad LK<CR> Only the keypad is locked and the terminal displays the message "KEYLOCK" Unlock keypad UK<CR> The keypad is unlocked Command for changing the current unit of measurement (if a secondary unit of measurement is handled) CU<CR> (CUb<CR>) 2-38

39 Remote commands with checksum Management of remote commands with checksum can be enabled during the installation phase (par on page 2-87). Checksum mode increases security when the terminal and PC dialogue with each other since the following precautions are taken: each remote command transmitted to the terminal must contain two checksum characters in a dedicated position; each reply with data that the terminal transmits to the PC after a remote command must contain two checksum characters in a dedicated position. The position of the two checksum characters is immediately prior to the <CR> character.. Checksum calculation involves making the XOR (exclusive OR) of all the characters in the string up to the first checksum character excluded. The result is expressed by two hexadecimal characters. An example of a gross weight transmission with checksum is given below: XB chk1chk2 <CR> where, supposing that value 1A is obtained from XOR: chk1 is the first checksum character ("1" or rather 31H) chk2 is the second checksum character ("A" or rather 41H). The terminal replies with the following string: n<sp><um><sp>b chk1chk2 <CR><LF> n = 9 characters (see par on page 2-9). 2-39

40 Remote commands with addressing When using the string "On request with address" or if the RS485 communication interface is selected, the remote commands described in par on page 2-26 will also have to include the number of the terminal to be interrogated. The system is comprised of one Master terminal (e.g. a PC) and a number of Slave terminals (e.g. weighing terminals). Each weighing terminal is identified by a unique "terminal number" (see par on page 2-87). In this way you can create a network of weighing terminals that can be interrogated by the Master terminal. The syntax of the remote commands has to be modified by the addition of the two characters of the terminal number. For example, the gross weight transmission command XB <CR> becomes XB 01 <CR> to indicate that the request from the Master terminal is addressed to the terminal number 01. Similarly, in checksum mode the gross weight transmission command becomes XB01 chk1 chk2 <CR>. No reply will be sent by the terminal if there are checksum errors. 2-40

41 10.5 Remote commands for Output management How to set a single output Output n2 of slot n1 can be set by means of the following command: SO n1 n2 <CR> where: n1 is 1 hexadecimal character that defines the slot position of the output; n2 is 1 hexadecimal character that defines the number of the output on slot n1. n1 = 0 (30H) output on the terminal n2 = 1 (31H) output number 1 n2 = 2 (32H) output number 2 n2 = 3 (33H) output number

42 How to zero-set a single output Output n2 of slot n1 can be zero-set by means of the following command: RO n1 n2 <CR> where: n1 is 1 hexadecimal character that defines the slot position of the output; n2 is 1 hexadecimal character that defines the number of the output on slot n1. n1 = 0 (30H) output on the terminal n2 = 1 (31H) output number 1 n2 = 2 (32H) output number 2 n2 = 3 (33H) output number

43 How to test a single output The status of each output can be requested by means of the following command: TO n1 n2 <CR> where: n1 is 1 hexadecimal character that defines the slot position of the output; n2 is 1 hexadecimal character that defines the number of the output on slot n1. n1 = 0 (30H) output on the terminal n2 = 1 (31H) output number 1 n2 = 2 (32H) output number 2 n2 = 3 (33H) output number 3 The terminal replies with one of the following messages: 1<CR><LF> if the output is activated; 0<CR><LF> if the output is not activated. 2-43

44 How to test all the outputs The status of all the slot outputs can be requested by means of the following command: LO<CR> The terminal replies with the following string: n1<cr><lf> where: n1 is 1 character that is the logic combination of the status (0 or 1) of the outputs (max. 3) on the terminal. Its values can be 0 (30H) to 7 (37H). The lines will be arranged in the following way: bit2 bit1 bit0 line 3 line 2 line 1 where the line values are 0 or 1 (0 = not activated, 1 = activated). For example, if the following command is received: 7<CR><LF> bit2 bit1 bit Out3 Out2 Out1 2-44

45 How to change the status of all the outputs The status of all the slot outputs can be changed by means of the following command: n1wo<cr> where: n1 is 1 character that is the logic combination of the status (0 or 1) of the outputs (max. 3) on the terminal. Its values can be 0 (30H) to 7 (37H). 2-45

54 10.7 Communication in MPP operation Operation Terminals equipped with the MPP option can operate in the four different modes described in the following paragraphs. The operating mode used for MPP memory operation is selected during installation (par on page 2-86). 2-54

55 Weighing request from keypad with data transmission on completion of operation After having enabled the MPP memory (consult the Options chapter of the user manual), load the weight onto the scale, wait for weight stable signal, then press. The terminal will save the weight data in memory and then transmit them. If the Standard item has been selected in the Setup Menu (par on page 2-86), the data transmitted are: 1 st character 2 nd character 3 rd character 4 th -10 th character 11 th -18 th character 19 th -20 th character 21 st -22 nd character $(24H) M(4DH) P(50H) <um> <CRC> MPP identification code or scale status indications: NO<SP>STAB weight not stable NO<SP>VAL<SP> weight not valid ERRMEM<SP> weight memorisation error Weight with sign and decimal point, if present Unit of measurement String check field; calculated by performing an XOR operation (exclusive OR) of all the preceding characters. The value calculated is expressed in two hexadecimal characters, e.g. if the result is 62H, the two checksum characters are "6" (36H) and "2" (32H). 2-55

56 If the Terminal number item has been selected in the Setup Menu (par on page 2-86), the data transmitted are: 1 st character 2 nd character 3 rd character 4 th -6 th character 7 th -13 th character 14 th -21 st character 22 nd -23 rd character 24 th -25 th character $(24H) M(4DH) P(50H) <um> <CRC> MPP terminal number MPP identification code or indications about the scale status: NO<SP>STAB weight not stable NO<SP>VAL<SP> weight not valid ERRMEM<SP> weight memorizing error Weight with sign and possibly a decimal separator Unit of measurement String monitoring field. 2-56

57 If the Serial Number item has been selected in the Setup Menu (par on page 2-86), the data transmitted are: 1 st character 2 nd character 3 rd character 4 th -11 th character 12 th -18 th character 19 th -26 th character 27 th -28 th character 29 th -30 th character $(24H) M(4DH) P(50H) <um> <CRC> Serial number MPP identification code or indications about the scale status: NO<SP>STAB weight not stable NO<SP>VAL<SP> weight not valid ERRMEM<SP> weight memorizing error Weight with sign and possibly a decimal separator Unit of measurement String monitoring field. The computer replies with: <ACK> if the string has arrived correctly; <NAK> if the string has not arrived correctly; in which case the terminal retransmits the data packet. After three negative replies or no reply, the terminal displays an error message. Any characters other than <ACK> and <NAK> are interpreted as <NAK>. WARNING The ACK/NACK protocol (see par on page 2-25) is automatically enabled in MPP operation. 2-57

58 Weighing request from serial command with transmission on completion of operation After having loaded the weight on the scale, send the memorise weight and data request command via the computer: MP<CR> (MPb<CR>) If the response is affirmative, the terminal will transmit one of the strings described in par on page 2-55 in the same mode, depending on the item selected in the Setup menu (Standard, Terminal number, Serial number) Weighing request from keypad and transmission request from serial command After loading the weight on the scale, wait for the weight stable indication and then press ; the terminal will memorise the data. The computer may request the weight data from the terminal with the command: MP<CR> (MPb<CR>) The weighing terminal replies: with one of the strings described in par on page 2-55; NP<CR><LF> if no weight has been memorised; The data may requested more than once with the command MP<CR>. At the end of the operation, the computer must transmit the command to enable the terminal to carry out a new weighing operation: MP<CR> (MPb<CR>) 2-58

59 Weighing and transmission request from serial command After loading the weight on the scale, send the memorise weight command from the computer: MP<CR> (MPb<CR>) Once the weight validity conditions are satisfied, the terminal memorises the data. The external computer must then transmit the data request command: MP<CR> (MPb<CR>) The terminal responds with the string described in par on page MP and MC remote commands with checksum Remote commands MP and MC modify their structure for entry of the checksum characters. Their format becomes the one below: MP 1 D <CR> MC 0 E <CR> 2-59
